WINDOW OPENING AND CLOSING MECHANISM.

Application led .Tune 16, 1920. Serial No. 389,277.

T all whom vit 'may concern.'

Be it known that we, HARRY E. NoRwoon and FREDERICK G. MAIER, citizens of the United States, Aand residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Window Opening and Closing Mechanisms, of which the following is` a specification.

Our invention relates to mechanism for operating windows to close or open the window opening and particularly relates to mechanism for operating double windows, that is, it relates to suchcases wherein `two or more panesor panels of glass are employed to close a single window opening.

The invention is particularly useful in connection with the windows of automobile closed bodies although it may be applied to other uses wherein yit is desired to-have all parts of the .window travel in the same direction.

In some parts of automobile bodies as well as in some constructions of bodies the well .cient depth to permit a one part window yto drop down far enough to completely clear the whole window opening from the sill to the top. Therefore when the window has sible it still projects above the sill and prevents obtaining the advantages of the full window opening. This is the case 1n the partition in back of the drivers seat in most limousine bodyl constructions and also exists in many constructions in connection with the windows at the rear seats of the body and particularly when employing mechanical means for raising and lowering the windows.

The object of our invention is to permit the Window opening to be fully exposed particularly when employing mechanical means for raising and lowering it and when the well is not deep enough to take a single window of the size of the window opening.

A /urther object is to reduce the time necessary to close or open the window and to effect the desired result in a simple, efficient manner.

A still further object is to provide a mechanism for carrying out the above objects which will be free from rattle and liability to get out of order.

In carrying out the invention theuwindow is divided longitudinally into preferbelow the window opening is not of suiiibeen dropped into the well as far as pos ablytwo4 parts and in such case in opening or closing the same, the one part travels at twice the speed of the other part so-that thetwo parts lie alongside each other in parallel planes in the well when the window opening is fully exposed.

The invention consists in the mechanismfor opening and closing double windows as hereinafter more particularly described and then s ecified in the claims.

In t e accompanying drawings.:

Fig. l is a front elevation of a double window construction in accordance with this invention.

Fig. 2 is an enlarged vertical Across-sectaken on the line 4-4 Fig. 2.

Fig. 5 is a similar section'taken onthe vline 5-5 Fig. 2.

Fig. 6 is a similar section taken on the line 6-6' Fig. 2.'

Fig. 7 is a similar sectiontaken on the line 7-7 Fig. 2.

For simplicity of construction and operation it is preferable to divide the window horizontally into but two parts or sections and it is so shown and Will be so described and when so divided the upper part or section travelsA at twice the speed of the other lower part but it will be understood that the window may be divided intoa greater number of parts all connected for'operation together and in which one part may travel at a diilerent relative speed to the other part or parts than twice the speed Without departing from the spirit of this invention.

Referring to the drawings l and 2 indicate the usual channels secured to the frames at each side of the Window opening and in which "channels the window travels in its movement to expose or close the window opening.-

3 indicates the well into which the window drops when lowered, the well being located below the sill 4 and in back of the inner partition or panel 5 (see Figs. 2 and 3).

6 and 7 indicates the panes or panels of glass comprising the double window o-r sections of window. These panes are located tion taken on theline 2-2 of Fig. 1 and in parallel planes, one forward of the other and so positioned that when in completely closed position, one part slightly overlaps the other.

The lower pane 7 is seated in and carried by a channel' 8 to which is connected a' mechanical raising and lowering mechanism of any suitable kind and typified at 9 which is located in the well below the window and usually in a well in the door and below the window opening.- Mechanical means for lraising and lowering the windows -of -automobile bodies are now universally employed and their' mode of operation is well understood by those skilled in the art. A construction of` such mechanism. suitable for use .with our invention is shown and described in United States Patent No. 1,218,130, dated March 6th, 1917 and, as Well understoodin the art, upon rotating the operating handle, which is connected with the sprocket 12, in one direction or the other the lower pane 7 or lower section ofthe window will be raised or lowered as the case maybe dfue' to the pin 10 working in the slot 11 of the pla-te 13, said plate being connected with the channel 8.

Ateach side of the windows 6 and 7 and located in the channels 1 and 2 the mechanism connecting the window panes or sections of window together is located. For

, the purpose of sustaining or providing means for attachment of the mechanismto the upper section of the window, an angle strip 14 may be cemented to each vertica'l edge of the upper pane or section 6 and similarly a chan-- nel strip 15 may be cemented or secured toeach vertical edlge of the lower section or lower pane 7. ach strip 14 carries at its lower end a block 16 in which a lug or pin 17 or other device is mounted for the attach- V ment of a suitable cable or rope preferably of metal, employed as will be presently described. Mounted upon each strip 15 of the lower section and at or near the upper edge ofthe section is a pulley 18 and on each strip at or near thelower end ithereof is simivlarly mounted a pulley 19.

2O indicates wire cable which may be endless but which, operatively considered/ n o Q o comprlses two sections. A s1m1lar section is provided at each edge or side' of the lower section of the window. A section of cable 'at one side of the lower section is attaehedat one end to a block 21 suitably fastened to the sill 4 of the door or casing lin whichthe window receiving well is located. The other end of said section ot rope passes over the upper pulley 18 on the same side of the window and extends down-l tion to the block 21 at one end and at the other to a pinor lug 17. and is carried over a similar pulleyV 18. Another section of cord attached to the block 21 or to other suitable fixture passes down and around the pulley 19 at the lower edge of the lower section and then up for attachment to the lower edge of the upper section of window by means of the rejecting pin or lug 17 or other device. X similar section of cord is similarly connected and passes over a pulley in a similar way at the opposite edge.

In the operation of the device, upon actuating the Vmechanism 9, the lower pane 7 is moved up or down due to its connection therewith. This travel of theA pane 7, carrying the pulleys-18 and 19 with it, causes a.

corresponding travel of the pane 6 in the same direction due to the connection with the cable 20, the cable being fixed by its connection 21 and being sustained in lany desired lifting position by the means usually employed in the art.

When the lower section is lowered by the operation of the mechanism 9, the upper sectionv is lowered at twice the speed by the operation of the two movable pulleys 19 which move with the lower section and have sections of cable, each attached at one end, running over them and attached at one end to the sill 21 and at the other end to thelower rail or edge of the. upper section.

Thus by the time the pane 7 has been dropped completely into the well 3 the pane 6 is also completely in the well and substantially flush with the pane 7 as indicated in Fig. 3. When the lower section is raised by the mechanism 9 the upper section is raised by the action of the two pulleys 18 upon the two sections of cord or cable which are attached at one end to the fixture 21 and pass up and over the pulleys 18, and then down for connection with the attachment 17 at the lower edge of the upper section. This movement, obviously, owing to the action of the movable pulleys 18, produces movement of the upper section at double the speed of the lower, so that when the pane 7 has been completely raised, the pane 6 or upper sec- .tion will have closed the upper part of the Isufticient depth to take a window half the size of the window opening and also the speed of opening and closing the window is greatly increased over those caseswhere a single window is employed to close the entire window opening. It will be seen that the upper section or pane 6 is at all times sustained by the lower section and that the position of rest of the latter which is determined by the raising mechanism 9 or by any suitable means, will determine'the extent of the adjusted window `opening above the upper edge of the pane 6. Also, it will be seen that the upper section being sustained at both edges, it is not liable to bind in the channels.

What we claim as our invention is 1. In a double operating mechanism, for windows divided horizontally into two sections the combination with means for raising and lowering the lower section, pulleys secured to said section near its upper horizontal edge and a cable passing around said pulleys and connected with and sustaining the other section whereby uponl imparting movement to the first section the second will travel in the same direction at double the speed and will be sustained by the lower section in any adjusted position thereof.

2. In a window operating mechanism, a-.-

plurality' of windowsl for a single window opening, means for raising and lowerlng connected to the lower window, pulleys carried by said window near its upper edge and also near its lower edge and a cable secured at a fixed point and passing around said pulleys, said cable being secured to the upper window whereby upon movement of the first window the other window will travel in the same direction but at a different relative speed and will be sustained by said lower window in all adjusted positions thereof.

3. In a double window operating mechanism, for a window divided horizontally into sections raising and lowering means connected to one window, pulleys carried by said window, at or near its upper edge and at both sides thereof", sections ot a cable secured to the window sill and passing around said pulleys and a stud connecting the other window at each side near its lower edge to said sections of cable as and for the purpose described.

4. In a window operating mechanism, a plurality of windows for a single window opening. mechanical raising and lowering means connected to the lower window in the well below the window opening, pulleys secured to the top and bottom of said window at each side thereof and a cable passing over said pulleys at each side of thewindow, each cable being anchored at a fixed point and attached at a different. point to the yupper window and serve to sustain the upper Window as well as operating it in both directions, whereby, upon operating said means, all the windows will travel in the same direction but at relatively different speeds.

5. A window operating mechanism for carriage windows comprising two sections having an actuating mechanism connected with and operating upon the lower 'section to raise and lower the same, pulleys attached to both edges of the lower section near the top thereof as well as near the bottom, sections of cable fixed at one end to the window Jr'rame and passing up and over the upper pulleys and down for attachment to the lower edge of the upper section, other sections ot cable fixed to said window frame and passing down around the pulleys at the lower edge of the lower section and up for attachment to the lower edge of the upper section and means within the well below the window opening for operating the lower section to raise and lower both sections while at the same time sustaining the upper seotion from the lower, all of said parts being fully housed within thel well when both sections are fully lowered.
